Page 5: Specifications
Temperatures Service 20,000 lifting cycles, when used and maintained as intended Life 1..Available with other rubber compounds for special purposes (see www.wpg.com). 2..Standard with replaceable sealing rings for rough or textured surfaces (see “REPLACEMENT PARTS”). 3..The Maximum Load Capacity is rated at a vacuum of 17.5" Hg [-59.25 kPa] on clean, smooth, nonporous flat surfaces with a friction coefficient of 1. Pad compound, load rigidity, strength, surface conditions, overhang, angle, center of gravity and temperature can also affect the lifting capacity. -
Page 6: Safety
SAFETY Wear personal protective Do not use hand cup to lift cracked equipment that is appropriate for or broken glass the load material. Follow trade association guidelines. Make sure the contact surfaces of the load and vacuum pad are clean Do not attach the hand cup to before attaching the pad (see hoists or any other lifting device. -

OPERATING FEATURES Features shown here are underlined on their first appearance in each section following. VACUUM PAD PLUNGER RED-LINE VACUUM INDICATOR HANDLE VACUUM RELEASE BUTTON VACUUM PUMP (VENTURI) 1/8” NPT MALE FITTING Note: A standard N4950AIR handheld vacuum cup is shown. Although some of the following photos do not show this specific hand cup, they all illustrate how this kind of hand cup functions. -
Page 8: Assembly
ASSEMBLY 1) Remove the handheld vacuum cup (hand cup) from its carrying case or remove the pad cover, depending on the model. Save the case or cover for future use. 2) Connect the hand cup to an appropriate compressed air supply (see Power Source under “SPECIFICATIONS”): Use appropriate hose and/or fittings... -
Page 9: Intended Use
1..Although concave vacuum pads can also attach to some curved loads, curvature can reduce lifting capacity. Contact WPG for more information. 2..Vacuum pads made from a heat-resistant rubber compound can enable you to lift loads with higher surface temperatures. Contact WPG or an authorized dealer for more information. -
Page 10: Operating Environment
INTENDED USE PERATING NVIRONMENT Make sure the hand cup is intended for use in each work environment, given the following restrictions: • This hand cup is not intended for any environment Never use hand cup in that is dangerous to the operator or damaging to dangerous environme nts. -
Page 11: Operation
OPERATION EFORE SING THE Determine whether the hand cup is capable of each intended task (see “SPECIFICATIONS” and “INTENDED USE”). Then complete the following preparations: Taking Safety Precautions • Be trained in all relevant industry and Read all directions and safety regulatory standards in your region. - Page 12 OPERATION Center the hand cup on the load (fig. 2A). Make sure the entire sealing edge of the vacuum pad is in contact with the load. Press the hand cup against the load until the vacuum pad seals against the contact surface. the pad seals, the plunger should automatically retract into the handle,...

Page 13: T O Lift And Move The Load
OPERATION IFT AND OVE THE Interpreting the Red-Line Vacuum Indicator A red line on a plunger serves as a vacuum indicator. When the red-line vacuum indicator (arrow in fig. 1A) is hidden, vacuum is sufficient for lifting. Never lift load when red-line indicator is visible, because this action could result in load release and personal injury. -
Page 14: In Case Of Power Failure
OPERATION In Case of Power Failure A power failure at the compressed air supply could result in a load Set load down release and personal injury, unless action is taken immediately: Lower immediately the load immediately to the ground or a stable support, and if power failure discontinue hand cup use until power is restored. -
Page 15: After Using The Hand Cup
OPERATION FTER SING THE Disconnect the hand cup from the compressed air line (see “ASSEMBLY”) or turn off the compressed air supply, as appropriate. Caution: Do not set the hand cup against any surface that could soil or damage the vacuum pad. -
Page 16: Inspections And Tests
2..The Periodic Inspection is also required whenever the hand cup has been out of service for 1 year or more. Keep a written record of all Periodic Inspections. If necessary, return the hand cup to WPG or an authorized dealer for repair (see “WARRANTY AND... -
Page 17: Maintenance
MAINTENANCE ACUUM AINTENANCE Pad-to-Load Friction Coefficient The friction coefficient represents the hand cup's ability to resist load slippage. The Maximum Load Capacity is based on a friction coefficient of 1, as determined by testing of a clean, new, standard rubber vacuum pad on clean, dry, regular glass. If the hand cup is used under any other conditions, a qualified person must first determine the effective lifting capacity. -
Page 18: Pad Cleaning
4) Allow the pad to dry completely before using the hand cup. 1..A brush with bristles that do not harm rubber can help remove contaminantes clinging to sealing edges. If these cleaning methods are not successful, contact WPG or an authorized dealer for assistance. #35105... -
